warco lathes.

I've just looked at my 280V with the inverter drive and 1.5kw motor and it definatly says 1 phase, also the wiring out of the inverter is single phase, you can see the terminal which looks like it would be for a 3rd phase.

But I can see the removable panel, that could be handy.

You will see from the above schematic from the WM250V manual, the motor is most definitely a 3 phase type

The motor is the symbol with the M in it.

The Inverter takes a single phase domestic 240V supply and converts to 240V 3 phase. The motor is wired in delta configuration.

Hi thanks everyone again for your replies , I have now sourced a lathe not a warco but a vice roy hope to collect soon . Ill keep you posted. Gareth

Yes that's the same as mine but the motor plate definitely says 1 phase, can't load the picture I took.
I thought it should be 3 phase as well, maybe it is and the motor plate is wrong?

Not a problem anyway, it all seems to work and even seems fine on high speed range with the lowest motor speed.

Steve

Steve,

uploading pictures is not as straightforward as most forums, have a read of this thread it explains how to do it.

Graeme

You were right, it is 3 phase, it's the fan that's single phase.

They must have decided to run the fan separately to cool the motor better when it is turning slowly.

Do the Warco mini lathes take a 10mm tool ? I thought most small lathes of this size took an 8mm tool ?

Hi, my Warco minilathe takes a 8mm tool and is a good small lathe, just upgraded it after 12 years to bigger warco lathe which is fine but I will the small lathe for odd special jobs.

Gareth, Bought a Warco GH750 in either 2000 or 2001 and the only thing I did to it was to remove the original single phase motor and replaced it with a Eurotherm vfd [now made by Parker SSD ] and a three phase 3hp Siemens motor. The lathe is still accurate to this day never any problems. The only thing I have ever had "go " on me was the halogen worklight bulb, and that must have been after a good few years. This model is not made now

cheers.

For nearly thirteen years, have used a clone of the Warco BH600, and the only problem has been of my own making. It came fitted with the option of a VFD; which is invaluable, (for someone as lazy as me).

Originally, the worklight consumed Halogen lamps much too frequently. Thinking that the cause was probably excess temperatures; stripped out the "reflector" and filled a couple of diametrically opposed slots in the rim. Since then, lamp failure is almost unknown. So, if lamps keep burning out, try improving ventilation of the lamp housing.

The BH600 is available as the Chester Craftsman. If you wanted a Warco just paint it green.

I have a Warco 240MV purchased march 2016

I have a problem that is getting worse & having no idea about electrics I am becoming concerned.

When I press the start button there is the usual loud click & often nothing happens. I then press the stop button ( Not the large main cut off one) & then the green button & the lathe normally starts. However, I now have to repeat the process up to 3 times to get the lathe to start, so something is developing into a fault. I always turn the speed down before starting & wind the cutter back so less load before starting. I assume that is correct !!

In addition the lathe will suddenly stop dead for a second, then start when i am turning.As an example, it did this yesterday when I was boring a hole in steel with a carbide boring bar at 925 RPM so i do not believe that i was loading the machine unduly

Has anyone had this issue & can they point me in the likely direction for rectification

Thanks

Sam,

Firstly, check for loose wires and fuses...Unlikely but needs eliminating.

I'd go for the motor, check the brushes are in good condition and are free in their holders.

If that doesnt improve things, then I would connect a domestic 40 watt light bulb across the mains wiring connected to the speed control board, use this as a monitor. The bulb should light and stay lit all the time unless there is an issue with the nvr switch.

After these steps a more in depth investigation is required. Keep us posted on your progress.

Sam,

Does your machine have the Delta inverter drive with the 3 phase AC motor. I have the identical fault, been ongoing now for about 6 months. The problem is totally random, starting at different RPM makes no difference, it will either go or not.

I have contacted Warco about this but no remedy has been found.

I have a Warco 240MV purchased march 2016

New or second hand? If new it must be still under warranty or only just outside? Contact Warco should be route to go. They should know the typical faults, either way.

No idea. It was new when i bought it.. I undid the front panel & waggled some wiring & the fault has stopped--- for now it would appear !!!

Cannot read the label on the back as the lathe is bolted down & against a wall.

That is the obvious action -- bit like RTFM i suppose.

Will call them Monday, although this afternoon fault has stopped so it seems to be one of those awkward ones

Thanks John

I was OK up to " 40 watt light bulb" then you lost me--- so it will be a call to Warco on Monday

Actually the real problem is that when i installed the lathe I placed 4 pieces of 225mm catnic lintol down first & leveled & bolted  them down including fixings at the back by the wall. I then lifted the lathe on its Warco bench onto these to give me a 225mm higher lathe. So it is not just a case of undoing a couple of bolts & easing it forward as I have to hire an engine hoist to get it off the catnics just to open a back panel. So it all gets a little messy.

I did the same with the mill & it really helps with my back as everything is so much higher for working.

Trouble is that getting any  panels off will be expensive to start with before I even get to look inside

Instead of hiring a crane to get it down get a pallet or two and some ply topping to make a temporary floor in front to slide it onto.

I'm also not a happy bunny with Warco for similar reasons as Rik Shaw...

I bought a new lathe from warco based on the old BH600 I owned which was a good machine

Lathe 1, GH1236, Finally delivered after 12 weeks (was told they lost it) with large amounts of paint falling off, rusty, bolts missing, panels bent and won't fit, threaded holes without threads in them, general poor quality - RETURNED

Lathe 2, Dropped and smashed during delivery by Warco staff - RETURNED

Lathe 3, After little use following ill health it has melted all the wiring and circuit boards - warco inform me that they only cover parts after 6 months so I have to pay to have it inspected and repaired. they will provide parts only !! Not what you expect from a so called good company with an excellent reputation

Currently awaiting said parts !!!
